Specifically, the invention aims to provide novel means for housing the inner tube and protecting thesame, the inner tube being made eilicient as a means for aflording the desired resiliency. y

Another object of the invention is to provide, novel means whereby the necessary movements may be permitted to take place, anti-irictionally, \between the tire and the rim. i

It is within the province of the disclosure to improve generally andito enhance the utility of devices of that typeto which the present invention appertains.

With the above and other objects in vievi which Will appear as the description proceeds, the invention resides in the combination and arrangement" of parts'and in the details of construction hereinafter described and claimed it being understood that changes infthe precise embodimentof the invention herein disclosed can. be made Within the scope of what is claimed, without departing from the spirit of the invention.

Fig. 8 is a composite perspective showing disposing of the rim 1 in a circular form.

T he beveled ends 4 of the terminal sections of the rim 1 may be united. by a removable plate 5, although this element may be dispensed with or changed, should occasion demand. The rim 1 embodies a base 6 and side flanges At intervals, the inner faces of the side "hinges 7 are provided, as indicated in Fig. 5, with spaced, parallel ribs 8, defining a recess 9 therebetween. Fitting into the recess 9 is a back plate 10 embodying a top flange ll and ends 12 extended across the ribs 8,-the ends 12 terminating in lips 14 which bear against the side edges of the ribs 8. Cooperating with the back platell) is a closure plate 15 through which protrude -anti-friction balls 16, the closure plate 15 being provided with openings 17 which serve to permit, dirt to find its way out of the pocket defined by the closure plate 15 and the top flange ll, so that the balls 16 may run freely. The c csure plate 15, ordinarily, is held in place by a securing element 18 passing through the back plate {above described but preferably located 90 degrees removed from each other are wear plates 2O set into and held in recesses 19 formed on the inner faces of the side This detail is best disclosed in Fig. 7. Extended longitudinally of the rim 1 and located in the angles defined by the flanges 7 and thebase 6 are buffers 21, preferablyin theform of rubber strips. ,The invention comprises a tire QQ'WlllCll may be madeofflmetal, the tire22 being.

preferably flattened as shown at 23,,and provided adjacent its flattened portion 23 with longitudinal si'de ribs 24. Atroughshaped metal shoe 25 is heated and shrunlronto the flattened surface 23 of the tirc 22 between the side ribs. Seated in the shoe is a tread 26 which maybe mat '15 29 receiving plates 80 (see Fig. 4) provided at their ends with pockets'v31including balls 32. The balls 32 coact with the strips 14 shown in Fig; 5, and the balls'16 as shown inrFig. 5 coact with the plates 7, 30, suiiicient circumferential play being permitted, so thatthe resilient features of the wheel will in'no wise be impaired. Seated in recesses 33- and in the side flanges 28 of the tile, as "shown in Fig. 7, are box-like casings 34, one of which isshown in Fig. 8, the casings 34 preferably being; held in place by securing elements 35. Seated'in the box-like casings 34 are two-part ball retainers 36, the constituent members of I which, as Shown i Fig. 8, are united by securing'elements 37, the ball retainers '36 carryingballs 38 adapted to coact with the fwear plates, 20. i a

Interpqsed between the flanges 28 of the tire 22 are tubular sleeves'39. Screws 40 are passed through the flanges 28 and are threaded into the ends of the'sleeves 39. A skilled mechanic will appreciate readily thatthe screws 40 may be replaced by bolts, 40 but screws, ordinarily, will be found more eflicient than bolts, since, by the use of the screws, the protruding nuts on the bolts may be avoided; s v 7 V The invention comprises a trough-shaped v support 41, ordinarily fashioned from'metal, :thesupport 41 embodying side flanges 42, the support 41'being inverted, as shown in v Fig. 3, and the inner edges of the side flanges 42 resting on the base -6 of the rim. .In the. side flanges 42 of the support4l openings 43 are fashioned, thesejopenings being adapted to receive the sleeves 39and the screws 40 which connect opposed side flanges 28 of the tire 22, the construction being such that the necessary movement in the tire 22, parallel-to the median plane of ,7 the structure, may be permittedv The trough-shaped support 41 preferably comprises. a plurality of sections 44, the ends of "which abut, one endof each section being provided, as shown in Fig; 6, with inset ,Wings 45, adapted to be received between the, side flanges 42 of the next sectionof the support. As indicatedin Fig. 1, the 165 flendsjofcertain of the sections of the troughthe base; a trough-shaped support inverted bOdying flanges slidably receivedj between theflanges of the rim and the support and shape -s ppo 4 e beve edatqh eci i the mounting of the supportzin place, the V beveling above alluded to being designated by the reference character 46. i

Upheld by the support 41 is an annular shoe 47 of trough-shape, the shoe 47 ordinarily being made of rubber or somelgres1lient substance of a like sort. The longtu'dinal edges of the shoe 47 overlap the side portions of the tire 22 as clearly shown '75 in Fig. 2 of thedrawings. lnterposed between the shoe 47 and the tire 22 is a-tube 48 'made of rubber or some similar substanceandadapted tobefinflated by any suitable means, "not shownfbut well understood in the-art L', 1" I ..I In practical operation, the tube 48 'is inserted into-the 'tire -22, the sleeves 39 being removed. The shoe 47 is then mountedin place, the support} 41 is inserted, the-rim 1 85. is disposed in annular form, as shown in Figs; l and '3," the T sleeves '39 having been previously mounted in 7 placebetween -the flanges 28 of the tire 22. or

-l Vhen the partsxar'eset up asabove described, the'tube 48 will afford the necessary resiliency, and permit the tire 22 to move radiallyof the wheel, with respect to the demountable -rim" 1, the anti-friction devices "above described being so constructed that, :although the necessary movement radially between the tire 22v and the rim'l may be permitted, excessive creeping will at the in same time,be avoided}: r V i -Having thus described the invention, what is claimedis:.-

1. In a device of the class described, a. rim embodying a base and side flanges; spaced resilient cushioning strips lodged in the angles defined by the'side flanges and onthe rim and engagingthe rim between the cushioning strips the support being provided Jwith lateral openings 5 a the emadapted to 'coact with the cushioning-strips; securing devices connecting the flanges of the tlre and received in the openingsof'the support; and acushioninterposed betw'eenllli the support and the' tread portion of the tire. p Y j 2. Ina-device of 'theplass described, a rim includmg a base and side fianges;'- a

tire having side fiangesdisposed betweenthe side flanges 'ofthe rim,on e side fiange'of the rim'and one sidejflange of thetire coni stituting cooperating -elements, one' of said cotiperatmg elements havinga. lateral recess;

anti fric tion devices located at'the end f 51- the recess; a casing projecting fro'mthe other of sa d; cooperating elements and entering the-recesstolimit relative circumferentialcreeping between therim and the tire, the anti-friction "devices coacting with the ifao ends of the casing; and anti-friction devices carriedrby the casing and coacting With that cooperating element which is provided with the recess, at the base of the recess.

8. In a device of the class described, a rim including a base and side flanges, one of the side flanges being provided With ribs; a casing disposed between the ribs; a tire including side flanges disposed between the side flan es of the rim, one of the side flanges 0 the tire being provided With a recess in which the ribs are received, to prevent the creeping between the tire and the rim; anti-friction devices carried by said flange of the tire and located at the ends of the recess the anti-friction devices coacting with the outer edges of the ribs; and antifriction devices carried by the casing, the last specified anti-friction devices cooperating With the said flange of the tire at the base of the recess.

In testimony that I claim the foregoing as my oWn, I have hereto aflixed my signature in the presence of two Witnesses.
